6 Claims. (Cl. 129-1) This invention relates to binders and moreparticularly to binders for books and the like, such as telephonedirectories, which may be frequently referred to.

An object of the invention is to provide a binder of durable and sightlyconstruction for the purpose of publicly displaying telephonedirectories and the like and primarily adapted to withstand rough usageand malicious tampering at the hands of the public and also, in thefield, to provide means for ready replacement of parts damaged by use.

A further object of this invention is to provide a binder adapted tohold a book or other object for pivotal movement on a longitudinal axis.This invention relates to my co-pending application, Serial No. 470,082,filed November 19, 1954, for a patent on a book rack filed herewith,which is designed for use in combination with this improved binder.

With these and other objects in view the invention consists of certainnovel features of construction and combination and arrangement of partswhich will be more fully hereinafter described and pointed out in theclaims.

Fig. 12 is a schematic transverse sectional View of five binders havingflexible side covers mounted in my improved book rack.

The binder combines four elements comprising a back plate and side coverassembly, a depressible arched inner platform plate, a book-couplingtongue and a longitudinal pivot and supporting rod.

Referring to the accompanying drawings by numerals, as shown in Figs. 1,2 and 3, the back plate and side cover element includes a metal backplate 1 having perpendicular side walls 2 and end walls 3 forming arigid box-like structure, the side walls terminating in hinge knuckle 4at their free edges and having complementary hinge leaves 5 attachedthereto by loose hinge pins 6 formed at one end with an angularextension 7, as shown in Fig. 4, the said complementary hinge leaves 5having attached thereto side covers 8 which may be of rigid materialsuch as Masonite or Bakelite or they may be of flexible material such asleather, paper or plastic. The said end walls 3 extend beyond the sidewalls and terminate in a curvedice edge 9, each end wall being providedwith a plurality of key-hole shaped apertures 10 spaced apart andpositioned on an arc concentric with the projecting curved edge 9 asshown in Fig. 2 and also having aligned round apertures 11 positionedtherein. The said apertures 11 may be positioned on the longitudinalcenter line of the binder or laterally to the right or left thereof asdesired.

As shown in Figs. 6, 7, 8 and 9 the depressible inner platform elementincludes an arched plate 12 having downwardly projecting parallel sideflanges 13 and perpendicular end brackets 14 as shown in Fig. 10 inwhich are positioned elongated slots 15. Located in the side flanges 13near each end are rectangular apertures 16 through which are insertedthe free ends 20 of the compression springs 17 preferably made of flatspring wire and formed as shown in Fig. 11 into a bow-shaped base 18with upwardly projecting side flanges 19 and inwardly projecting endextensions 20 having a round aperture 21 therein. Positioned in thearched surface of the platform plate and aligned with the apertures 21in the end extensions of the springs are elongated slots 22.

As shown in Figs. 1, 3 and 5 the book coupling tongue consists of anarrow strip of metal 23 formed symmetrically at each end with a roundedperpendicular extension 24 adapted to be inserted through the key-holeshaped apertures 10 in the end walls 3 of the back plate and being ofsufiicient length so that the end extensions 24 will project beyond thesaid end walls.

As shown in Figs. 1, 2 and 3 the longitudinal pivot and supporting rodconsists of a round metal rod 25 adapted to be passed through theextruded apertures 11 of the end walls 3 of the back plate and alsothrough the elongated slots 15 of the platform plate and being ofsuflicient length to project at each end beyond the said end walls 3.

On assembly of the elements in operative engagement the side covers 8are first attached to the complementary hinge leaves 5 and coupled tothe back plate hinge knuckles 4 by inserting the loose hinge pins 6which when fully projected into the respective hinge knuckles arerotated inwardly so that the hinge pin extensions 7 lie fiat against theinner surface of the side walls 2. The fiat compression springs 17 areassembled to the depressi'ble platform plate 12 by inserting into therectangular apertures 16 the free end extensions 20 of the springs asshown in Fig. 11. When mounted in this manner as illustrated in Fig. 9,the laterally projecting shoulders of the springs will normally extendoutwardly from the sdie walls of the platform plate which is then nestedinside the back plate by exerting external pressure to force the saidshoulders downward and below the inwardly projecting hinge knuckles 4 ofthe back plate in which position the shoulders will spring outwardly andlock the platform plate securely in operative engagement as illustratedin Fig. 2. The bow-shaped base 18 will bear upon the inner surface ofthe back plate and exert an upward pressure to hold the platform platein its normal operative position with the said shoulders locked underthe hinge knuckles. The rod 25 is then passed through the respective endapertures 11 of the back plate assembly and the elongated slots 15 ofthe platform plate so that the two plates are locked by the rod toprevent their accidental separation.

It is to be noted that the arched surface 12 of the platform plate, thecenters of the key-hole shaped apertures 10-and the curved edge 9 of theend walls 3 are concentric and in register and that the arched surfaceof the platform is normally positioned at the juncture of the roundsection and the stem of the key-hole shaped apertures as illustrated inFig. 2. By reason of the resiliency of its supporting springs, theplatform plate is adapted to be temporarily depressed by manuallyexerted external pressure sufiiciently to entirely expose thekeyholeshaped apertures.

A tongue 23 is then assembled to the binder by depressing the platformplate at one end in the manner described so that the key-hole apertureis fully uncovered and the end extension 24 of the tongue. may then bepassed therethrough. Upon repeating this, operation at the opposite end.and shifting the tongue longitudinally both end extensions 24arepositioned outside of the end walls 3. Thereupon the externalpre'ssure is released and by reason of the upward thrust of thecompression springs under the platform plate the tongue is locked atboth ends against accidental longitudinal movement. It is also to benoted that the diameter of the circular section ofthe key-holeaperturein which the tongue is confined is equal to the width of the'tongue, sothat when the tongue is thus locked'in operative engagement it is. stillfree to rotate from side to side in the said aperture. a

The binder is primarily designed for the display of telephonedirectories or the like 'for' useby the public.

It is designed for durability and cleanliness and stainless steel ispreferably employed for the construction of such metal parts as aretouched by human hands. It is also designed with a view to minimizingmalicious tampering at the hands of the public and at the sametirneitoafford means for the repair or replacement bya service man ofparts damaged by use or other cause in the field.

Fig. 12 illustratesa diagrammatic transverse sectional view of fivebinders installed in my improved book rack for public use. They arespaced apart and mounted on supporting-rods 25 which are attached ateachend to uprights 26 integral with the shelf-27 of the rack. Coupled tothe binders are a series of telephone directories 28. To couple atelephone directory 28 or'the like to a hinder the book is first laidopen at the center and a tongue 23 is laid between the parted pages atthe spine with one end protruding from the book. The'book is thereuponpositioned with its spine resting on the platform plate which is thendepressed at one end to enable the protruding tongue. to enter thekey-hole aperture. Thereafter the opposite ,end of the tongue is securedin the manner above described and the directory is securely coupled tothe binder for movement in any direction. One or more directories maybecoupled to the same binder to the limit of its capacity.

ltis to be noted that when a paper bound book such a telephone directoryis laid open for reading, the

. spine of the book normally assumes an incurved or concave contour andthe reading of the innermargins of the pages is thereby greatlyfacilitated. Thearched surfaces of the platform plate-12 is'designed topreserve the concavit" of the spine of the book when coupled to thebinder so thatthe reading of the-inner margins of the page is therebygreatly facilitated. It is further to be pointed out that asthe pagesare turned to the right or left of center the coupling tongue isenabledto rotate from side toside and following-the contour of the pages and tolay fiat between them and at the same time the binder is enabled torotatefrom side to side on its longitudinal supporting and pivoting rodwhich features further promote the legibility of the inner margins ofthe pages. i

For the purpose of guarding against malicious tampering and yetproviding means for servicing in the field the major elements are lockedtogetherby the supporting and pivoting rod and this rod must first beremoved to disassemble the parts for repair. t

To disengage the platform plate assembly from the back plate theelongated slots 22 in the platform plate give access to the roundapertures 21 positioned in the will be freed from the hinge knuckles andthe platform plate thereby disengaged and removed fromthe back late. pThe loose hinge pin extensions 7 which have been held captive by theside walls 13 of the platform may now be rotated and withdrawn from thehinge knuckles and the side covers damaged by use may be readilyreplaced. At the same time the platformplate assembly may be likewiserepaired by a service-man in the field.

While. I have illustrated and described what I believe be the-preferredembodiment of my invention,-itis obvious that changes may be made in thegeneral 'form and arrangement ofth e parts without departing from thespirit of. the invention; hence, I consider myself; at'liberty to makesuch changes and alterations as fairly fall within the scope of theclaims.

2. A binderin accordance with claim 1 in which the back plate andv sidecover assembly comprisesa flatcm'etal back plate having perpendicularend and side wallsforming'a rigid box-like structure, said sidewallste'rminating in inwardly projecting hinge knuckles, a complementaryhinge leaf having side covers attached thereto andbeing joined to the.said hinge knuckles by loose hingeq pins each having an-angularextension at one end which 'extension upon assembly is rotated inwardlyof theL-back' plate to lie fiat against the inner surface of the sidewalls and is prevented by the said end walls from accidentallongitudinal movement, upon assembly of the :said resilient platformplate nested'inside the back plate the. said angular end extension ofthe loose hinge pinsarc engaged thereby and prevented fromrotation-whereby the hinge pins are locked in operative engagement andcan only be removed from the binder for the repair or replacement ofparts damaged by use .by first removing the platform plate.

3., A binder in, accordance with claim 1 in 'which the depressible innerplatform plate comprises an arched or curved plate having parallel flatside walls and perpendicular end walls, the said side walls havingrectangular apertures near each endand below the arched surface;

bow-shaped fiat wire compression springs dependin from the sidewallsand.havinginwardly projecting e nd extensions; projected .into: thesaid rectangular apertures so as to form external lateral shouldersoutside the said apertures, the platform plate being assembled to theback plate by nesting it inside thereof by exerting external pressure tocompress and force the said shoulders to a position inside and beyondthe inwardly projecting hinge knuckles of the side walls of the backplate so that the said shoulders upon release and expansion will belocked in operative engagement under the said hinge knuckles and bearingagainst the said side walls of the back plate with the said bow of thespring being compressed and bearing upon the flat inner surfaces of theback plate so that the platform plate while thus locked in operativeengagement by the outward thrust of the bow spring against the shoulderlocks and rendered depressible against the back plate and thereupon theopposite end of the platform is depressed to allow the tongue to beentered in the key-hole slot and the directory is securely coupled tothe binder in operative engagement.

4. A binder in accordance with claim 3 in which the book coupling meanscomprise a depressible inner arched platform plate, a book couplingtongue formed of narrow metal strip having a self formed perpendicularextension at each end, adapted to be entered into key-hole shapedapertures radially disposed in the end walls of the back plate and inwhich the radius of curvature of the said arched surface of the platformplate and the center line of the key-hole shaped apertures areconcentric, the latter apertures consisting of the conventional circularbulbous outer portion merging into a straight stem-like inner section,the said arched surface of the platform plate being normally positionedat the point of juncture of the said bulb and stem sections of thekey-hole apertures, so that when the platform plate is sufiicientlydepressed at one end to entirely expose a key-hole aperture, then oneend of a coupling tongme is inserted and moved longitudinally thereinwhereupon the opposite end of the platform is depressed to fully exposea second key-hole aperture and the opposite end of the coupling tongueis then entered therein and shifted longitudinally so that both endextensions protrude equally beyond the said end walls so that the tongueis prevented from further longitudinal movement but is enabled to rotatein the key-hole aperture as the pages are turned from side to sidewhereby when external pressure on the platform plate is released furtheraccidental longitudinal movement of the tongue is prevented by the endextensions and when a paper bound telephone directory is mounted on theplatform plate and a tongue passed between the page: thereof, thedirectory is securely coupled to the binder and the normal concavity ofthe spine is maintained so that the reading of the inner margins of thepages is greatly facilitated.

5. A binder in accordance with claim 4 in which a paper bound telephonedirectory is positioned on an arched platform so that the normalconcavity of its spine is thereby permanently maintained and securelycoupled to the binder by a tongue inserted between the leaves at thecenter of the book and engaged at both ends in the circular bulb of thekey-hole shaped aperture in which the flat metal tongue is designed torotate and follow the contour of the pages accordingly and lay flatbetween them whereby when the book is opened for reference and theleaves are turned from side to side the inner margins are more clearlyexposed to view and the reading thereof is greatly facilitated.

6. In accordance with claim 1, a telephone directory binder adapted forfrequent and prolonged use by the public and designed to minimizemalicious tampering comprising two major interdependent co-operatingelements consisting of a platform plate formation nested inside a backplate structure, both of said plates being formed with perpendicularside and end walls, the said respective end walls of the back platehaving aligned round apertures therein intermediate the sides, the saidrespective end walls of the platform plate having elongated slotstherein aligned with said round apertures of the back plate, the saidside walls of the platform plate having compression spring means toenable the platform plate to be depressed in cooperation with bookcoupling means of the back plate for coupling a directory to the binder,the said sidewalls of the back plate terminating in inwardly projectinghinge knuckles, side covers attached to the said knuckles by a loosehinge pin having an angular extension at one end which upon assembly isrotated inwardly to lie flat against the side walls and prevented by theside walls of the platform plate against counter rotation and removal, asupporting and pivot rod passing through the aligned apertures in therespective end walls of the two plates whereby the two major elementsare locked in operative engagement and the malicious removal of the saidhinge pins or tampering with the compression spring mechanism of theplatform plate at the hands of the public is prevented.
